Patent CA-2056356-C (CA)
Inventor: UENO HARUHIKO
IPC: G06F9/38
Filed: 1991-03-19
Granted: 1998-06-09
Abstract: An interruption processing system enables a basic CPU resource using process to be executed asynchronously, enabling an interruption handler to be easily created.          Interruption handling of the basic CPU resource using process enables an original program to be resumed after a corresponding interruption handler process is terminated for a CPU resource using process dependent interruption factor.          The interruption processing system comprises a queuing unit for determining whether an instruction stored in an instruction buffer designates a synchronous process or an asynchronous process and for queuing the instruction when it is an asynchronous process.  When more than one asynchronous process which has been queued is terminated unprocessed or with exceptions in the case where an interruption is generated in a synchronous processing unit or an asynchronous processing unit or an interruption from the outside of a CPU is detected, contents and termination methods of all asynchronous processes terminated unprocessed or with exceptions at the time of the generation of the interruption are displayed in order to resume a program prior to the generation of the interruption.

Abstract: A solid-state electrochromic device is disclosed comprising tungsten oxide-Prussian blue complementary configuration in combination with a proton-conducting polymer electrolyte.  A novel proton-conducting copolymer, especially useful in transparent electrochromic cells, comprising the reaction product of a vinyl sulfate monomer with a comonomer selected to form an alternating copolymer, such as vinylpyrrolidone, is disclosed.  Novel transparent complementary electrode materials for electrochromic cells are disclosed, of the general formula [M1]4[M2(CN)6]3 wherein M1 may be indium, gallium, gadolinium, lanthanum, and M2 is iron.  Unlike Prussian blue (where M1 and M2 are both iron), the complementary electrode materials of the present invention are stable, and do not have to be precharged.  An electrochromic transparency comprising an electrochromic film and an ion-conductive layer disposed between a pair of electrodes is disclosed wherein the optical properties and electrochromic efficiency are improved by means of a metal grid electrode, wherein adhesion of the metal grid to an acidic polymer electrolyte is improved by means of a primer coating comprising a copolymer of acrylamidopropane sulfonic acid and acrylic acid.

Title: System and method for treating sewage or other fluids
Inventor: VANDERVELDE DONALD M
IPC: B09C1/00
Filed: 1991-01-14
Granted: 2001-06-05
Abstract: This invention lies in the field of on-site sewage and wastewater treatment.  Standard on-site septic systems require special soil and groundwater conditions with large lot sizes. This invention comprises a method and device for complete treatment of sep-tic tank effluent or other contaminated water by contriving for it to flow in an ultra-thin film over a surface treatment medium such as fabric or sand, providing diffusive aeration, biological reaction, and physical filtration on a molecular scale. The device transfers contaminated water from a container (48) to a final collector (42), completely purifying the liquid in the process. The pu-rified effluent can then be reused for household, industrial, irrigation or other uses, or disposed of as normal surface run-off in streams or lakes. To increase efficiency, said container encloses a progressively more finely pored media (18, 22, 26, 28, 32) pre-cisely situated with effluent seeping gradually through progressively finer pores to provide effective pretreatment.

Title: Method and apparatus for image registration in a single pass ros system
Inventor: COSTANZA DANIEL W
IPC: H04N1/047
Filed: 1992-09-09
Granted: 1999-06-01
Abstract: A single pass ROS system provides a plurality of latent images which may subsequently be developed in different colors. The ROS units are initially aligned so that each color image is precisely registered at the same relative position along the exposed area of a photoreceptor belt. The alignment is accomplished by forming a pair of opposed alignment apertures in the surface of the belt and detecting coincidence or lack of coincidence of signals generated by the beginning and end of each scan line. The skew correction is enabled by rotating an optical component in the ROS system to create the required rotation of the projected scan line so as to correct for the detected skew error caused primarily by belt conicity. Once the initial X and Y-axis alignments are complete, subsequent alignment is maintained through subsequent passes by checking the positions of the previously identified pixels as they advance past additional lead edge apertures formed in the process direction along the belt surface.

Abstract: A method of controlling a rock drilling process by adjusting the percussion power and the feed force of a drilling machine. In the method, the drilling is carried out automatically in stages so that the percussion power and the feed force as well as drilling time or drilling depth are adjusted at a start-up drilling stage, and the ratio between the percussion power and the feed force is adjusted at a transition stage while increasing them until the set value of normal drilling is achieved. In normal drilling, the feed force is adjusted so that the rotation power remains at the set value.

Abstract: The presence of a crack in a material and the orientation of the crack is determined by placing a transducer  on  the  surface  of  the  material for propagating a shear wave for reflection off of the back wall of the material. The reflected signal is evaluated such that no signal or a weak signal indicates the presence of a crack.  The transducer is then held in place and rotated while propagating a shear wave in order to determine the orientation of the crack.  The reflected shear wave is then evaluated in the same manner.

Abstract: A process of separating at least one mineral, e.g. silica, from an aqueous medium, e.g. one containing iron ore, by froth flotation using cationic alkyloxyalkaneamine collectors free of acrylonitrile is described.      Alkyloxyalkaneamines free of acrylonitrile may be made by reacting an alcohol with an alkenenitrile having at least 4 to 13 carbon atoms. This process produces branching on the third carbon from the nitrogen of the resulting compound, e.g. 3-hexoxypentaneamine. In addition to the absence of acrylonitrile, the alkyloxyalkaneamines give better selectivity than some conventional etheramines.
